What did you do to your Supra today?

[ntvaribl]

It wasn’t today, but this week, car came back from shop after some installs and tune. Pure900, do88 manifold, 1050 injectors, BMR catch can, BMS intake, motiv reflex+, flex tune. My shop/tuner took these photos

Couple of things to note:

Coolant temperatures are very stable on heavy load in general and compared to stock. I have the Wagner Tuning Manifold. This was a really good purchase.

The manifold has zero to do with coolant temps. That is a completely different cooling circuit.

Yes. But do they actually work or are they just pure marketing?

They do, but do you need one? Ideally, oil is above 212F/100C to boil off the condensation in the system. Ideally ideally, you maintain a temperature around 230F. These values are higher than many people expect. On my last car, it was a real struggle to get oil above 190 and all these goofballs were running around installing giant oil coolers anyways. That oil needed to be HOTTER, not colder. They should've used a tstat to control flow into the cooler, and they probably didn't need one at all.

So, if your oil is cookin' at 260F+, yeah, an oil cooler will help and is a good idea. But if you're streeting the car and seeing temps like 230, that's great. Keep it and do nothing.

Had a Helmholtz resonator fabricated to combat drone from ~1900 to ~2300 RPM - seems to do the trick too.

What single exit is that?

Custom built.

Custom built.

I need to find someone to do a custom job for mine, did that resonator change exhaust note at all?

Not that I can tell - other than I can actually hear the exhaust around 2k rpm now...

Yup. There's a huge misconception that oil needs to be as cold as possible. Just like brake pads, there is a temperature operating range that they should be at.

My winter beater/track rat is an N54 335i and last summer I did a plethora of cooling upgrades so that it would survive track sessions without going into limp mode. The N54 runs even hotter than B58, so managing temps was a struggle. I finally did enough to keep temps in check, but this winter in the Mid-Atlantic has been brutal with temps not exceeding 40F in past few months.

Until I can swap the thermostat to a 212F unit, I'm having to resort to cardboard in front of cooling stacks to reduce airflow so that I could get my temps into a more desirable range. Even drove without turning on the heat in single digit temps just to keep the heat isolated to the engine

Undestood. But I live in Miami and on Jan 23 the oil temps peaked and stayed at 260F. In January.

51 degrees in Alb, NM (Lowes run)

While the Supra's cooling system is much better than my N54, yes, I think it could benefit from an oil cooler. Just adding that there is a such thing as running stuff too cool.

260F isnt that bad honestly if it was stable. Most good engine oil will be stable against shearing at that temp.

Are you using 50/50 mix of coolant?
Running higher percentage of coolant to distilled water will lower temps (I ran 90% water to 10% coolant during summer, then switched to 30/70 during winter).

 

[razorlab]

260F is fine. 275F+ for extended periods is when you have to start reeling yourself in.

I have hit 280F a couple times and did oil tests, no issues. However, I do run the infamous 5w40 oil that hard parkers like @concept think will cause space and time to fold upon itself.

Also, a tune can tweak all the coolant targets which will also help with oil cooling/not cooling.

Two days late but new daily to go with Supra…
